but there are OH groups also so i thought that it could be alcohol but its not like that right
and also same q paper q 7 biii.......................pls
Depends on the q, here its vitamin C. Usually all vitamins contain -OH groups. Only for the structural formula you need to specify -OH and not the molecular formula.
For Q.7 b)iii) There are 'n' number of types of chlorination. This depends on how
much chlorine you use and
which hydrocarbon you use.
When chlorination occurs it replaces one hydrogen atom from the hydrocarbon and forms HCl
E.g. Chlorination of methane::
H H
| |
H- C - H + Cl
2 ------> H- C - Cl + HCl
| |
H H
CH
4 + Cl
2 ---->
CH3Cl + HCl
Product::
Chloromethane (methyl chloride)
Similarly,
CH
3Cl + Cl
2 ---->
CH2Cl2 + HCl
Product::
Dichloro methane (methylene chloride)
CH
2Cl2 + Cl
2 ---->
CHCl3 + HCl
Product::
Trichloro methane (Chloroform)
CH
3Cl
3 + Cl
2 ---->
CCl4 + HCl
Product::
Tetrachloro methane (Carbon tetrachloride/Pylene)
I think you only need to know the names in bold. For your question, choose any of the following reaction BUT using butane and chlorine
Eg. C
4H
11Cl + Cl
2 ----> C
4H
10Cl + HCl
OR to be safe give acc. to the ques
CH3-CH2-CH2-CH2-Cl + Cl2 ----> CH3-CH2-CH2-CHCL2 + HCl
H H H H H H H Cl
| | | | | | | |
H-C-C-C-C-Cl + Cl-Cl----> H-C- C-C-C-Cl + H-Cl
| | | | | | | |
H H H H H H H H
Don't understand anything.. pls. ask.. Just under the concept of chlorination
they may ask any other alkane next time
Draw the structures yourself you'll understand better
